Control Which Document Types Can Be Created in a Folder

Introduction

Goal

Control which document types can be used to create documents in a folder.

Reasons

1. Help authors organize and structure their content by minizing the number of decisions they have to make.
2. Simplify delivery tier implementation using wildcard sitemap items (e.g. /products/**.html matching all documents in the /products folder and its subfolders) by making sure all matched documents are of the same type.

Method

The list of document types that can be used within a folder is the result of a query. The default query returns all document types. By configuring a different query for a folder, the document types that can be used in that folder can be restricted.

The following two use cases are described:

• Using Document Types Included with Out-of-the-box Features
• Manual Configuration for Custom Document Types

Optionally the following can be (manually) configured in both use cases:

• Use a Custom Icon

Before	After

Using Document Types Included with Out-of-the-Box Features

When using out-of-the-box features from the library (such as News or Events) typically any folder created by the feature is already configured to allow only the document type that is included in the feature.

Additional folders can be created and their restrictions configured through the CMS UI.

Example

This example assumes the "News" feature has been added to the project, and an additional folder "press releases" has been created which must be restricted to only allow "news" documents to be created inside it.

In the Content application, browse to the "press releases" folder and select Edit allowed content... from the popup menu:

The "press releases" folder has the generic default queries configured (Add new translated folder and Add new document).

Remove both queries by hovering the mouse cursor over the Actions column and clicking on the X icon.

Select Add new news folder and Add new news item from the dropdown at the bottom of the dialog:

The "press releases" folder is now configured to only allow "news" document to be created, as well as "news folders" which applies the same restriction recursively to subfolders:

Click OK to apply the configuration changes.

The context menu for the "press releases" folder now no longer contains the generic Add... options, but has Add new news folder and Add new news item instead:

Manual Configuration for Custom Document Types

If the project contains custom document types (i.e. not part of an out-of-the-box feature), corresponding template queries must be defined to be able to set up restrictions.

You can use the Template Query Generator (part of the Essentials development tools) to generate template queries for your custom documents.

It's also possible to define custom template queries through manual configuration using the Console, as described in the example below.

Example

Goal: configure the folder /content/documents/myproject/products to restrict new documents to the document type myproject:product.

1. Configure a Query for the Product Document Type

1. In the console, copy the node

   /hippo:configuration/hippo:queries/hippo:templates/new-document

   to

   /hippo:configuration/hippo:queries/hippo:templates/new-product

2. Limit the queried document types to myproject:product:

   /hippo:configuration/hippo:queries/hippo:templates/new-product:
     jcr:statement: //element(*,hipposysedit:namespacefolder)
                      /element(*,mix:referenceable)
                      /element(*,hipposysedit:templatetype)
                      /hipposysedit:prototypes
                      /element(hipposysedit:prototype,myproject:product)

   Note that only the last part of the JCR statement changes from hippo:document to myproject:product.

3. Change the i18n label(s):

   /hippo:configuration/hippo:translations/hippo:templates/en:
     new-product: new product

4. Save your changes.

2. Configure a Query for Sub Folders

The next step is the change the query to create sub folders in the products folder. These child folders should also limit the document types to myproject:product.

1. Copy the node

   /hippo:configuration/hippo:queries/hippo:templates/new-translated-folder

   to

   /hippo:configuration/hippo:queries/hippo:templates/new-product-folder

2. Change the JCR statement to create child folders:

   /hippo:configuration/hippo:queries/hippo:templates/new-product-folder:
     jcr:statement: /jcr:root/hippo:configuration/hippo:queries/hippo:templates
                        /new-product-folder/hippostd:templates/node()

   Notice the change of new-translated-folder to new-product-folder.

3. Change the available queries in a new product folder:

   /hippo:configuration/hippo:queries/hippo:templates/new-product-folder/hippostd:templates/hippostd:folder:
     hippostd:foldertype: [new-product-folder, new-product]

   Note that these values refer to the JCR node names of the queries we are creating in this example.

4. Change the i18n label(s):

   /hippo:configuration/hippo:translations/hippo:templates/en:
     new-product-folder: new product folder

5. Save your changes.

3. Configure the Folder to use the Queries

1. In the Content application, select the folder myproject > products.
2. From its popup menu select Edit allowed content. A dialog appears.
3. Remove any options currently configured.
4. From the dropdown add the options Add new product folder... (new-product-folder) and Add new product... (new-product).
5. Click OK to apply the configuration changes.
6. The menu for the "products" folder now contains the Add new product folder... and Add new product... options.

Use a Custom Icon

By default, one of the following two icons is used for the Add new... menu items:

• a folder icon if the query names ends with "folder" (e.g. new-product-folder)
• a document icon otherwise.

Optionally a custom icon can be used for any Add new ... menu item by placing an SVG icon with a viewport of 16x16 pixels in the following directory in your project:

cms/src/main/resources/org/hippoecm/frontend/plugins/standardworkflow

The file name of the icon must match the menu item's query name, postfixed with -tiny.

For example a custom icon for the query new-product would be stored at

cms/src/main/resources/org/hippoecm/frontend/plugins/standardworkflow/new-product-tiny.svg

After rebuilding and restarting the application the menu item will show the custom icon.
